Perfect for homes without existing ductwork or for adding climate control to a new addition, garage, or sunroom, ductless mini-split systems are an energy-efficient solution. Thermotech Heating & Cooling specializes in installing, repairing, and maintaining these versatile systems across King County. Unlike traditional HVAC units, mini-splits allow you to set different temperatures in different rooms, reducing energy waste and lowering utility bills. Our installation process is clean, quick, and minimally invasive. We help you choose the right size and number of indoor units based on your space and cooling/heating needs. Our technicians are factory-trained and up-to-date on the latest inverter technology, ensuring whisper-quiet operation and reliable performance. If your current mini-split isn't heating or cooling properly, we can diagnose and fix issues such as refrigerant leaks, sensor problems, or drainage clogs.
